The Effecting of Physical Properties of Inorganic Fillers on Swelling Rate of Rubber Compound: A review Study

Abstract

The purpose of preparing the review manuscript is to highlight the importance of the physical specifications of the most important of inorganic fillers such as "carbon black" and "silica" that have good physical specifications as surface area, particle size distribution and surface chemistry. Moreover, study the effect of these specifications on the resistance of vulcanized rubber compound for swelling, which is one of the disadvantages to determine the expansion of its uses in industrial applications through the review of many types of research in this area. The results proved that there is a strong relationship between the curing characteristics of the rubber compound such as the time of curing, the scorch time in addition to the "curing rate index' (CRI) and mechanical properties especially the tensile strength and "density of cross-links" for reducing the swelling rate to the minimum. By increasing the "density of cross-links" and improve the specifications of vulcanization and mechanical specifications.

The Influence of Microcrystalline and Nanofibrillated Cellulose in XSBR Polymers on the Mechanical Properties of Jute Textile-Reinforced Cementitious Composites

“…Despite the reduced peak load, a low scattering of results was observed. This is as indication that this solution provided a more uniform behavior throughout the fiber profile, as the coating with MCC seems to be dense and more compact due to the MCC filler effect, reducing polymer shrinkage and maintaining mechanical interaction with the cementitious matrix [8,19,38].…”

Evaluation of the physical properties and filtration efficiency of PVDF/PAN nanofiber membranes by using dry milk protein

“…Viscosity is one of the main parameters influencing the properties of nanofiber membranes, such as the fiber diameter, porosity, and pore size of the membrane fibers, especially when blending polymers such as PVDF and PAN [27,28]. Increasing the content of PVDF in the PVDF: PAN solutions led to an increase in the blend solution viscosity.…”

“…To evaluate the properties of the electrospun membranes, the microscale test was performed on the produced membrane samples on single fibers because of the difficulty and high cost of this type of assessment [28]. Field emission scanning electron microscopy (FE-SEM) was used to observe the upper surface at a certain magnification to determine the morphological properties of the membranes, such as diameter (nm), pore volume (μm3), and porosity (%), which were measured by ImageJ software.…”

Studying the Physical Properties of Non-Woven Polyacrylonitrile Nanofibers after Adding γ-Fe2O3 Nanoparticles .

“…The achievements of current nanofiber technology are one of the most important goals of modern research, which is produced by the electrospinning technique that allows the preparation of non-woven fibrous materials with distinct morphological properties such as fine diameters, high gas permeability [1][2][3][4], small fibrous pore sizes, large surface-to-volume ratio, highly disciplined porosity, and flexibility [5][6][7][8] .…”
